FASTENING FOR TOOL-HANDLES.

$PECIFICATION forming part of Letters Patent No. 447,707, dated March 3, 1891.

Application filed September 20, 1889. Serial No. 324,594. (No model.)

To all whom it may concern.-

Be it known that I, JULIUS YVEISS, of- Kiel, in the Kingdom of Prussia and German Empire, have invented a new and useful Fastening for Tool-Handles, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an iron or steel wedge fastening for handles of hatchets, axes, picks, heavy hammers, and the like. It is illustrated in the accompanying drawings, in which Figure l is a front elevation of the wedge or fastening constituting my invention, the pin a being in section; Fig.2, a side view thereof; Fig. 3, avertical cross-section of a hatchet with and Fig. 4; is an elevation partly in section and showing the lower end of the handle.

The object of my invention is not only to prevent the loosening of the handle, which is generally caused by the shrinkage of the wood, but to provide means for tightening the connection between the tool and handle automatically, Whatever may be the cause of loosening. For this purpose the wedge is constructed in the shape shown and also to facilitate its insertion and maintain its position in the handle. The longer, thinner, and more tapering end of the wedge which points to the lower end of the handle serves to spread the wood somewhat as the handle tends to loosen under the force of blows. The serrations or barbs b are provided to press into the wood and hold the wedge from receding or sliding. The opposite shorter wedge end serves to strengthen the handle at a weak point, and also by its form engages more readily and closely with the wood and aids to prevent the backsliding of the fastener into the notch of the handle.

In the drawings, 6 is a double-ended fishlike form of a wedge pointed at each end, but

the fastening applied thereto,

formed with a more acute angle at one end than at the other. At its widest part it is provided with a hole for the insertion'of a rivet, which serves to fiX it in position in the tool head and handle. The longer and thinner pointed end of the wedge when let into the handle 0 points to the lower end of the handle and is provided on both edges with serrations b in such manner that the points or edges of the serrations point in the direction of the opposite or upper end of the handle. The head of the tool is also provided with a hole to receive the rivet a, which secures the wedge to the handle.

The handle is first mortised or cut out sufficiently to receive the wedge. The head of the tool is then driven onto the handle, or the handle into the head, until the hole in the wedge and the hole in the head of the tool are in conjnnction,\vlien the rivet is inserted and headed down on the tool-head. By these means the handle is not only securely held in the tool, but should the handle get dry and shrink it is not loosened but held firmly in place.

hat I claim is- A fastening for tool-handles, consisting of a double-ended wedge with one end longer and thinner than the opposite end, the former end provided with serrations on its opposite edges and the larger end provided with a rivet-hole, in combination with a handle mortised to receive said wedge, and a tool-head also provided with a rivet-hole, whereby said wedge is adapted to be riveted in said handle and tool-head, substantially as described.

In witness whereof I have hereunto set my hand in presence of two Witnesses.

JULIUS \VEISS.
